A device (10) to compress a body part (68) comprising a user interface (12), a programmable logic controller (14), a power source (16), a source of fluidic pressure (18), valves (20,28) with ports in fluidic connection with the source of fluidic pressure, and a first and second inflatable bladders (26,34), wherein the programmable logic controller is programmed to cause the repeating sequence of inflating the first inflatable bladder by manipulating the ports of the valves, after a first preset period of time, deflating the first inflatable bladder and allowing the pressure within the first inflatable bladder to inflate partially the second inflatable bladder by manipulating the ports of the valves. The source of fluidic pressure can be a self-contained pump (38), a connection (40) to fluidic pressure in a health care facility, or a pressurized canister (42). The device has means to extend the life of the power source. |
